MIC94355 Description
The MIC94325, MIC94345, and MIC94355 Ripple Blocker™ devices are monolithic integrated circuits that provide low-frequency ripple attenuation (switching noise rejection) to a regulated output voltage. This is important for applications where a DC/DC switching converter is required to lower or raise a battery voltage, but where switching noise cannot be tolerated by sensitive downstream circuits such as in RF...
